Description
- The present invention concerns the field of bags provided with complementary closure profiles actuated by a slider.
- More particularly, the invention concerns a machine and method for placing a slider on complementary closure profiles, provided to be attached on a bag.
- Many bags of this type have already been proposed.
- Known in particular are bags formed from thermoplastic sheets, for example polyethylene and/or polypropylene.
- As illustrated in
FIG. 1 , theclosure profiles 20 used on such bags generally comprise complementary closure means 22 situated respectively opposite on the two main sheets making up the bag to be respectively made to engage in order to close said bag and separated to allow its opening. - The
sliders 10 equipping such bags can be the subject of many embodiments. Generally,such sliders 10 comprise abase 11 which includes twoside flanks 12 and acentral wall 13, theside flanks 12 and thecentral wall 13 defining together twonon-parallel channels 14 which respectively receive free ends ofprofiles 20. In a direction of movement of theslider 10, theprofiles 20 are stressed in separation to open the bag. In the opposite direction of movement, theprofiles 20 are engaged to close said bag. - In order for the
slider 10 not to be easily removed from the bag, in particular for safety reasons for children, it is usually provided with retaining means, for example of theflange type 15, arranged on the free end of thewall 13, complementary withprotuberances 21 forming a stop and situated on the free end of theprofiles 20, such that in case of attempt to tear the slider off of the bag, the flanges abut against theprotuberances 21 and prohibit removal of theslider 10. - One of the problems posed, however, in the field of closure profiles equipped with sliders, in particular when they comprise this type of retaining means, is that of the engagement of the sliders on these profiles.
- Means have therefore been proposed making it possible to elastically distance the flanks from the slider so that it can more easily be engaged on the complementary closure profiles, for example in French patent application FR 07 59545, filed Dec. 4, 2007 in the applicant's name.
- This technique indeed makes it possible to facilitate placement of the slider. However, it was noted that the
free end 21 of theprofiles 20 could abut against theend 15 of thecentral wall 13 of theslider 10, especially when the latter part is provided with flanges, thereby preventing the insertion of theprofiles 20 into thecorresponding channels 14 of theslider 10. Such a scenario is illustrated inFIG. 1 , for example. - The present invention therefore aims to overcome this gap, by proposing a machine for the automatic placement of sliders and a method for placing sliders, making it possible to facilitate the placement of a slider on closure profiles.
- Thus, the present invention proposes a machine for automatic placement of sliders, including in particular:
-
- a first supplier for supplying closure profiles, said closure profiles being provided with complementary closure means allowing the progression of closure profiles in said machine;
- a second supplier for supplying sliders; and
- a slider placement device;
also comprising a separator guide, situated opposite the slider placement device, said guide comprising a guide channel in which the closure profiles progress, the width of said channel being smaller than the thickness of the closure means, such that when the profiles are brought by the supply means into the separator guide, the closure means do not penetrate the guide channel while the portion underlying said closure means is squeezed by the walls of the guide channel, in order to separate the respective free ends of the closure profiles.
- Preferably but non-limiting aspects of the automatic placement machine according to the invention are the following:
-
- the width of the channel is essentially equal to the thickness of the portion of the profiles that underlies the closure means,
- the guide is a single piece, and the guide channel is a rabbet,
- the guide is made up of two adjacent units, and their adjacent walls are entirely or partially separated by the guide channel,
- the separator guide units can move in a direction transverse to the direction of movement of the closure profiles in the machine,
- the separator guide also includes a recess formed opposite the placement device, at the mouth of the guide channel,
- the recess has a hemispherical, conical or dihedral shape, the concavity of which is oriented toward the placement device,
- the materials making up the separator guide belong to the following group: plastic, metal, and
- the machine also comprises means for manufacturing a bag equipped with closure profiles provided with a slider.
- According to a second aspect of the invention, a method for placing a slider on closure profiles is proposed consisting of:
-
- providing closure profiles, said closure profiles being provided with complementary closure means, and having them progress in an automatic slider placement machine;
- providing sliders, said sliders comprising a base which includes two side flanks and a central wall, the side flanks and the central wall in combination defining two non-parallel channels which respectively receive free ends of the profiles; and
- sequentially engaging a slider on the closure profiles; the method also including a step during which the respective ends of the closure profiles are positioned opposite the corresponding channels of the slider and separated by squeezing by a separator guide of the portions of the closure profiles that underlie the closure means, so as to facilitate the engagement of the slider on said profiles.
- Other features, aims and advantages will better appear upon reading the detailed description that follows, and in light of the appended drawings provided as non-limiting examples in which:
-
FIG. 1 is a cross-sectional view of a slider and closure profiles during engagement of the slider on the profiles according to the prior art; -
FIG. 2 is a diagrammatic perspective view of a machine for manufacturing bags capable of being equipped with the automatic slider placement machine according to the present invention; -
FIG. 3 is a cross-sectional view of a slider and closure profiles upon engagement of the slider on the profiles according to one embodiment of the invention; -
FIG. 4 is a cross-sectional view of a second embodiment of a separator guide according to the invention; -
FIG. 5 is a cross-sectional view of the first embodiment of a separator guide illustrated inFIG. 3 ; -
FIG. 6 is a cross-sectional view of a third embodiment of a separator guide according to the invention; and -
FIG. 7 is a cross-sectional view of a fourth embodiment of a separator guide according to the invention. - The present invention can be applied to all types of bags. For that reason, we will not describe all of the means for realizing the bag itself in detail hereinafter, or its component material(s).
- The same is true for the
closure profiles 20. They are not limited to the geometry illustrated in the appended figures. Theseprofiles 20 can comprise closure means 22 of the male/female type, complementary Velcro/hook type, or any other equivalent structure. They can be made in any suitable material. - The
closure profiles 20 can be integral with the walls of the bag, for example by extrusion, or attached and fixed on the walls of the bag using any suitable means. - Lastly, the
sliders 10 implemented in the framework of this invention are of the type of the sliders we described in reference toFIG. 1 and will therefore not be described in further detail hereinafter. - The guide according to the invention is preferably implemented in the framework of the automatic placement of
sliders 10 onclosure profiles 20 to form thermoplastic bags. It is made in plastic or metal material, for example. - According to the invention, an automatic slider placement machine in particular includes means for supplying closure profiles, progression means of said profiles in the automatic machine, means for supplying sliders and a slider placement device. Of course, the slider placement machine can be part of a bag manufacturing, filling and closure machine, making it possible to manufacture bags equipped with closure profiles provided with sliders using said placement machine of the invention.
- One example of such a machine is illustrated in
FIG. 2 . Such amachine 1 in particular comprises: -
- a
first supplier 100 for supplyingclosure profiles 20; - a second supplier 200 for supplying
sliders 10; - a
device 400 for placingsliders 10, intended to sequentially perform the individual placement of eachslider 10 on theprofiles 20; - a
third supplier 500 for supplying athermoplastic film 30; - a shaping
neck 600 associated with afilling chute 610, which configures thefilm 30 from a flat initial state into a tube; - means 700 ensuring the longitudinal welding of the adjacent longitudinal edges of the film 40 and the fastening of the
closure profiles 20 equipped withsliders 10 on thefilm 30; and -
transverse welding clamps 800 associated with cutting means 900 in order to individualize the bags.
- a
- According to the invention, the machine also includes a
separator guide 300 arranged opposite theplacement device 400, the role of which is, on one hand, to guide theclosure profiles 20 during their progression in the machine such that they arrive in an optimal position in front of the placement device so that thesliders 10 can be correctly applied on theprofiles 20, and on the other hand, to separate theprofiles 20 in order to facilitate their engagement in the channels of the slider. - During the placement method of the
sliders 10 on theclosure profiles 20 in theautomatic machine 1, the placement device forcibly applies, conventionally, aslider 10 on thefree end 21 of the closure profiles. - Preferably, the placement device separates the side flanks 12 from the
slider 10, for example by stressing lugs situated on the outer faces of the side flanks of the slider (not shown in the figures), so as to free enough space to allow the engagement of theprofiles 20. Such a step is optional inasmuch as the invention can be applied to any method for placing a slider on closure profiles in which the slider is engaged on the free end of the profiles. - In parallel, closure profiles 20 are brought into the separating guide, such that the
free end 21 of eachprofile 20 is oppositecorresponding channels 14 of theslider 10. - Advantageously but not necessarily, the closure profiles 20 are closed when they are brought into the
separator guide 300, or at least their respective closure means 22 are in contact with each other during their passage in theguide 300. - Separating the
profiles 20 here means spacing the free ends 21 of theprofiles 20 that are intended to be arranged in the correspondingchannels 14 of theslider 10, such that said ends 21 move away from the plane defined by the closure profiles 20. - Indeed, it has been noted that when the ends 21 of the
profiles 20 are not parallel to each other and form an angle as illustrated inFIG. 2 , the engagement of theslider 10 onto the closure profiles 21 is improved due to the fact that said ends 21 avoid the obstacle formed by the central wall, and in particular get around theflange 15 of said wall, even if said ends 21 are provided with protuberances. - For this, the guide includes two essentially parallel stop walls forming a
guide channel profiles 20. The walls are arranged such that the width of thechannel guide channel channel - By pinching the portion 23 of the profiles underlying the closure means 22, the stop walls cause the
free end 21 of the profiles to move away by hinge effect, as indicated inFIG. 3 . Indeed, given that the closure means 22 are in contact, and preferably closed, the pressure exerted on said underlying portion 23 drives the rotation of eachfree end 21 around the axis formed by the closure means 22 in a separation direction relative to the plane defined by theprofiles 20. The ends 21 of theprofiles 20 are then no longer parallel to each other and present an angle that facilitates their insertion into the corresponding channels of thesliders 10. - According to one preferred embodiment illustrated in
FIGS. 3 to 5 , theseparator guide 300 is cast in one piece, and theguide channel 310 a is a rabbet whereof the height is at least equal to the length of the portion 23 of the profiles extending under the closure means 22. The walls of saidrabbet 310 a then correspond to the stop walls of theguide 300. - Alternatively, when the closure profiles 20 are integral with the walls of the bag or have been attached to said walls prior to the insertion of the
slider 10, the height of therabbet 310 a is at least equal to the length of the bag extending between its mouth and its bottom. - According to another embodiment illustrated in
FIG. 7 , theguide 300 includes twoadjacent units rabbet 310 a between them. - Alternatively to this embodiment, as illustrated in
FIG. 6 , theunits channel 310 b. - In the case where the
separator guide 300 includes twoadjacent units units profiles 20. - For example, in the case of a discontinuous manufacturing method, the automatic machine sequentially stops the progression of
profiles 20. Theunits guide channel placement device 400, simultaneously or successively, engages theslider 10 on said separated ends 21. Theunits profiles 20. - One can also consider implementing
units profiles 20 is not interrupted. Theunits profiles 20 during their progression, and theplacement device 400 engages theslider 10 simultaneously or successively to the pinching of theprofiles 20, without interrupting the progression ofprofiles 20. - Once the
slider 10 is engaged on theprofiles 20, it is sufficient to release the side flanks 12 of theslider 10, which elastically return to their initial position, thereby enclosing theends 21 of theprofiles 20. - Alternatively, as illustrated in
FIGS. 2 to 5 , theguide 300 also includes arecess 320 at the mouth of therabbet 310 a (or throughchannel 310 b formed by theunits slider 10, in order to further accentuate the opening of theends 21 under the pressure of theguide 300.
